(1) The high temperature environment causes problems such as melting of the coating material, solder joint opening, and structural changes in the stress in the elastic body. High-temperature resistant sensors are often used for sensors working in high-temperature environments; in addition, devices such as heat insulation, water cooling or air cooling must be added.
(2) The effect of dust and humidity on the sensor caused a short circuit. Under this environmental condition, a sensor with high airtightness should be selected. Different sensors have different sealing methods, and there are great differences in hermeticity.
Common seals are filled or coated with sealant; rubber pads are mechanically tightened and sealed; welding (argon arc welding, plasma beam welding) and vacuum nitrogen sealing.
From the point of view of sealing effect, welding sealing is the best, and filling and coating of sealant is the difference. For sensors that work in a clean and dry environment indoors, you can choose sensors that are glued and sealed. For sensors that work in a humid and dusty environment, you should choose a diaphragm heat-seal seal or a diaphragm welding seal and pump. Sensor for vacuum nitrogen filling.
(3) In a highly corrosive environment, such as moisture or acid, which damages the elastomer or short-circuits the sensor, the outer surface should be sprayed or stainless steel cover, which has good corrosion resistance and good airtightness. sensor.
(4) The influence of the electromagnetic field on the sensor output disorder signal. In this case, the shielding of the sensor should be strictly checked to see if it has good electromagnetic resistance.
(5) Flammable and explosive not only cause complete damage to the sensor, but also pose a great threat to other equipment and personal safety. Therefore, sensors working in flammable and explosive environments place higher requirements on explosion-proof performance: explosion-proof sensors must be selected in flammable and explosive environments. The sealed enclosure of this sensor must not only consider its tightness, but also The explosion-proof strength and the waterproof, moisture-proof and explosion-proof properties of the cable head should be considered.
